Abstract
Embodiments of the present invention provide a method and an apparatus for transmitting channel state information. The method includes: sending a feedback indication message, a high-efficiency long training sequence, and a resource scheduling message, wherein the feedback indication message is used to indicate more than one target STAs that need to feed back channel state information, the high-efficiency long training sequence is used for determining the channel state information by the target STAs, and the first resource scheduling message is used to indicate a communication resource used by the target STAs when the target STAs feed back the channel state information; and receiving the channel state information sent by the target STAs by using the communication resource.
